EPC cans on car shuts off after about 20 minutes of driving it. I haven’t driven the car in about two years now trying to pretty much sell it for scraps because I don’t know what to do with it can’t afford to get it worked on. Had somebody do a diagnostic with a Mitchell one program they came to the conclusion that was the alternator. I replaced the battery about six months ago in the car. Will turn over now, but still has a few lights on the dash in my throttlebody position center and pedal codes are popping up on my diagnostic code reader

After I drive to my job or anywhere and I turn off my car for a few hours, it turn off after driving it for less then 30 minutes nothing stays on the only thing that show it the dead battery sign, but I have replace the battery and how the alternator tested nothing pops up the only thing that shows on a scanner is a starter lock activation - short circuit to ground 03587-007 but I have been searching what that means but nothing seems to pop put or there will be many ways to fix it but nothing seems to make sense.

I have check alternator out is ok and wiring continuity also ok some time i have on the ignition found battery light is glowing for 10-15 seconds and off suddenly

New alternator after a week battery died car would not start
